Creating a VIP to Switch Contents Between Two Layer 4 Ports

This topic explains creating one virtual service to switch contents between two Layer 4 ports. Use the Layer 4 port switching feature on a Layer 4 virtual service if there are two VIPs listening on two different ports.

To create a single virtual service listening to two different ports (port X and port Y), create two pools – pool-X and pool-Y and add the servers to these pools.

Log into the Avi Load Balancer CLI and use the configure virtualservice <virtual-service name> to map one virtual service to two pools listening on two different ports.

Note:

This option is only supported through the CLI.

Creating a virtual service, and a pool to listen to port number X:

[admin:AviCloudController]: configure virtualservice L4-Test-VS
[admin:AviCloudControllert]: virtualservice> service_pool_select

[admin:AviCloudController]: virtualservice:service_pool_select> service_port x service_pool_ref pool-x service_protocol protocol_type_udp_fast_path
[admin:AviCloudController]: virtualservice:service_pool_select> where

service_port	x

Creating a virtual service, and a pool to listen to port number Y:
